But you wouldn't for one moment accept that in this way one can show how evolution gives rise to a god. It shows only how evolutionary processes may give rise to creatures who have the impression there is a god. So too for morality.
Unless I missed something, according to you, we only have an impression that there is morality. So we act as if there is. Maybe there really isn't. Correct?
Since you're unsure if morality exist, is there a need to even say that it has to come from an external source? When we don't even know if anything is there at all? In fact from the beginning you have mentioned several times that morality may very well be an illusion.
If I were you, doing the reasoning, I'll consider that quite a huge leap.
